“…It is known that to spin chitosan-based nanofibers, water-soluble fiber-forming polymers, such as PEO, PVA or methyl cellulose, are added to the solution. 3 It was shown that the electrical conductivities of chitosan solutions and liquid mixtures containing PEO are 2-4 mS/cm, that is, three to four orders of magnitude higher than the values for polymers with good spinning abilities in electric fields (aliphatic copolyamides and PVA). 4 The introduction of PEO causes a slight decrease in the electrical conductivity of a solution with a chitosan concentration of 7 % of mass fractions, but has almost no effect on the electrical conductivities of solutions containing small amounts of chitosan (3 % or 4 % of mass fractions).…”

The influence of chitin nanofibrils on the production of chitosan-based fibers is described in the article. The chitosan-based fibers and composite fibers were prepared from an aqueous solution of 2-% acetic acid using the coagulation method. The incorporation of 0.1-0.3 % of mass fractions of CNs into the chitosan matrix contributed to an increase in the mechanical properties of the composite fibers. The chitosan nanofibers were spun with electrospinning from a 70-% acetic-acid aqueous solution of chitosan containing 10 % of mass fractions of PEO and 1-30 % of mass fractions of CNs. The introduction of CNs into chitosan solutions accelerates considerably the quality of nanofibers at the electric field and decreases the amounts of defects in them. The optimal concentration of CNs for producing defect-free chitosan nanofibers was 20 % of mass fractions. Keywords: chitosan, chitin nanofibrils, wet spinning, electrospinning V~lanku avtorji opisujejo vpliv hitinskih nanovlakenc na procesiranje vlaken na osnovi hitozana. Vlakna na osnovi hitozana in kompozitna vlakna so pripravljali iz 2 % vodne raztopine ocetne kisline s koagulacijsko metodo. Vnos od 0,1 do 0,3 masnih odstotkov hitinskih nanovlakenc (angl.: CNs) v hitozansko matriko je prispeval k izbolj{anju mehanskih lastnosti kompozitnih vlaken. Hitozanska nanovlakna so spinirali (zapredli) z elektrospiniranjem iz 70 % vodne raztopine ocetne kisline hitozana, ki je vseboval 10 masnih % PEO (angl.: Poly Ethilen Oxide) in 1-30 masnih % CNs. Vnos CNs v hitozansko raztopino je znatno izbolj{al kvaliteto nanovlaken v elektri~nem polju in zmanj{al koli~ino napak v njih. Ugotovljena optimalna koncentracija CNs je bila 20 masnih odstotkov pri procesiranju hitozanskih nanovlaken brez napak. Klju~ne besede: hitozan, hitinska nanovlakenca, mokro in suho me{anje

“…Chitosan is a copolymer made up of 2-acetamido-2-deoxy-#-D-glucopyranose and 2-amino-2-deoxy-#-glycopyranose linked together through (1-4)-#-glycosidic bonds (Figure 12). Similar to alginates, different forms of chitin and chitosan such as gels, membranes, beads, microparticles, nanoparticles and nanofibres have been produced for various applications [51,166]. Chitosan is well-known for its unique antimicrobial activity and metal adsorption [182,183].…”

Abstract. Over the past decades, electrospinning of biopolymers down to nanoscale garnered much interest to address most of the millennia issues related to water treatment. The fabrication of these nanostructured membranes added a new dimension to the current nanotechnologies where a wide range of materials can be processed to their nanosize. Electrospinning is a simple and versatile technique to fabricate unique nanostructured membranes with fascinating properties for a wide spectrum of applications such as filtration and others. These nanostructured membranes, fabricated by electrospinning, were found to be of a paramount importance because of their advanced inherited properties such as large surface-to-volume ratio, as well as tuneable porosity, stability, and high permeability. The extensive research conducted on these materials extended the success of electrospinning not only to bio-based polymer nanofibres, but to their hybrids and their derivatives. The technique also created avenues for advanced and massive production of nanofibres. This paper reviews the recent developments in the electrospinning technique. Electrospinning of biopolymers, their blends and functionalization using metals/metal oxides, and the potential applications of electrospun nanofibrous membranes in water filtration are discussed.
